I try to fix it,but i can't Please help me!!

Hi,I am Really new in C++. I'm trying to write a program which search word from text file and display matched word whole lines. Can any body help me out please?


#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main()
{ int i;

char word[30];
char text[50];
fstream dict("bufferfile.txt",ios::in);

if (!dict.is_open())
{
cout << "Unable to open file";
system("pause");
exit(1);
}
cout<<"Enter word to search \n";
cin>>word;

loop:
i=0;
while(dict.getline(text,50))
{
while((word[i]!='\0')&&(text[i]!='\n'))
{ if(word[i] != text[i])
{
goto loop;}
else

cout<<text<<endl;


}
} ++i;
system("pause");
return 0;
}

A list of things to do:
Use code tags, realize you're programming in C++ not BASIC avoid goto , avoid system() whenever possible(it's slow, often unportable, and insecure in some cases), and reformat your code because someplaces look like errors but I can't tell.

Yes it some Error occured but i don't know hoe to deal with it.
If you know please help me,,thank you so much
